ABSTRACT
Purpose@#This secondary data analysis study evaluated the effects of ICT enhanced home-visit nursing in long-term care insurance on health-related quality of life among community-dwelling older adults. @*Methods@#This study included data of 131 older adults who had experienced a pilot service for ICT enhanced home-visit nursing. ICT enhanced home-visit nursing refers to a method of sharing health records and teleconference between a visiting nurse and a doctor during the home-visit nursing services to community-dwelling older adults. Health-related quality of life and influencing factors were analyzed by t-tests, logistic regression analysis using the Stata 17/SE program. @*Results@#After a pilot service for ICT enhanced home-visit nursing, their health-related quality of life increased. The teleconferencing method had a significant effect on the increase in health-related quality of life. @*Conclusion@#The findings indicate a pilot service for ICT enhanced home-visit nursing can be applied to the domestic community-based healthcare service model in terms of health management. In the future, the advanced service model of a pilot service for ICT enhanced home-visit nursing in which subjects conduct detailed for each health problem, and a well-designed evaluation system should be developed.
ABSTRACT
Purpose@#This study is to identify how the meaning in life, depression, and social support influences the suicidal ideation of old adult hemodialysis patients. @*Methods@#A cross-sectional design was used. A descriptive correlative study was conducted through an organized and structured self-administrated questionnaire survey for 120 sampled old adult renal dialysis patients. The collected data were analyzed by t-tests, ANOVA, Pearson's correlation coefficient, and multiple linear regression analysis using the Stata 13.0 program. @*Results@#The suicidal ideation of participants was positively correlated with the meaning in life, and social support, and the depression was negatively correlated with the suicidal ideation. Significant factors influencing the suicidal ideation included the meaning in life, depression, social support, age, caregiver, monthly income, and smoking. These factors explained 68% of the variance. @*Conclusion@#The depression of old adult hemodialysis patients was a major risk factor that increased suicidal ideation, and the meaning in life and social support was a protective factor that reduced the suicidal ideation. These results suggest that health professionals should provide old adult hemodialysis patients with proper management of suicidal ideation, and depression as well as its meaning in life, and social support.

ABSTRACT
PURPOSE: Charcot-Marie-Tooth disease (CMT) is a peripheral neuropathy mainly divided into CMT type 1 (CMT1) and CMT2 according to the phenotype and genotype. Although molecular pathologies for each genetic causative have not been revealed in CMT2, the correlation between cell death and accumulation of misfolded proteins in the endoplasmic reticulum (ER) of Schwann cells is well documented in CMT1. Establishment of in vitro models of ER stress-mediated Schwann cell death might be useful in developing drug-screening systems for the treatment of CMT1. MATERIALS AND METHODS: To develop high-throughput screening (HTS) systems for CMT1, we generated cell models using transient expression of mutant proteins and chemical induction. RESULTS: Overexpression of wild type and mutant peripheral myelin protein 22 (PMP22) induced ER stress. Similar results were obtained from mutant myelin protein zero (MPZ) proteins. Protein localization revealed that expressed mutant PMP22 and MPZ proteins accumulated in the ER of Schwann cells. Overexpression of wild type and L16P mutant PMP22 also reduced cell viability, implying protein accumulation-mediated ER stress causes cell death. To develop more stable screening systems, we mimicked the ER stress-mediated cell death in Schwann cells using ER stress inducing chemicals. Thapsigargin treatment caused cell death via ER stress in a dose dependent manner, which was measured by expression of ER stress markers. CONCLUSION: We have developed genetically and chemically induced ER stress models using Schwann cells. Application of these models to HTS systems might facilitate the elucidation of molecular pathology and development of therapeutic options for CMT1.

Muscle atrophy is the result of two opposing conditions that can be found in pathological or diseased muscles: an imbalance in protein synthesis and degradation mechanisms. Thus, we investigated whether exogenous melatonin could regulate muscle components in stroke-induced muscle atrophy in rats. Comparing muscle phenotypes, we found that long-term melatonin administration could influence muscle mass. Muscle atrophy-related genes, including muscle atrophy F-box (MAFbx) and muscle ring finger 1 (MuRF1) were significantly down-regulated in melatonin-administered rats in the gastrocnemius. However, only MAFbx at the mRNA level was attenuated in the soleus of melatonin-administered rats. Insulin-like growth factor-1 receptor (IGF-1R) was significantly over-expressed in melatonin-administered rats in both the gastrocnemius and soleus muscles. Comparing myosin heavy chain (MHC) components, in the gastrocnemius, expression of both slow- and fast-type isoforms were significantly enhanced in melatonin-administered rats. These results suggest that long-term exogenous melatonin-administration may have a prophylactic effect on muscle atrophy through the MuRF1/MAFbx signaling pathway, as well as a potential therapeutic effect on muscle atrophy through the IGF-1-mediated hypertrophic signaling pathway in a stroke animal model.
